WATER-PIPE BOILER.

SPECIFICATION forming part 0f Letters Patent NO. 702,954, dated J' une 24, 1902.

Application filed November 5, 1900. Serial No. 35,486. (No model.)

To [ZZZ ich/07711 it 71cm/ concern:

Be it known that I, HERMANN JANETSCHEK, a citizen of the Empire of Austria-Hungary, residing in Vienna, Austria-Hungary, have invented Improvements in Vater-Pipe Boilers, of which the following is a specification.

Myinvention has for its object a water-pipe boiler, and aims to obtain by a particular disposition of straight collecting-pipes an in-` tensely efficacious derivation of the nre-gases. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figures l and 2 are the above-mentioned boiler fitted with an upper boiler lying across in its front. Figs. 3 and 4 are the abovementioned boiler fitted with an upper boiler lying along. Figs. 5 and 7 are the plan view of the pipe arrangements without walling. The arrangement consists of the water-'pipes to and the standing collecting-pipes r. Figs. 6 and 8 are two cross-sections without Walling, showing two different pipe arrangements.

The horizontal rows of the water-pipes w are connected with the standing collectingpipes r, either as shown in Figs. 2, 5, and 6, the first lowest one following the lines a 7L, b c', c le, cZ Z, e m, from g o, ctc., the second following the lines a c', b 7c, c Z, (Z m, e mf o, &c., the third as the first, the fourth following the lines b 7i, c i, CZ Za, e Z, from g fn, dac., which arrangement is repeated regularly in the further rows of pipes. By this arrangement it will be seen that the pipes are arranged in series both vertical and horizontal, the horizontal series having its pipes in alinement, each series being spaced equidistant from the adjacent series. This allows of the formation of spaces within which may, if desired, be secured suitable deflecting-plates, as shown in Figs. l and 3. The vertical series, however, are out of alinement, excepting at their ends, so that there is an increased efficiency derived from the fuel in that the passage of the products of combustion is partially retarded by the breaking up of the straight fines between the several pipes. Or as shown in Figs. 4, 7, andS, the first lowest one following the lines c h, b t', c Zo, (Z Z, e ym, fn, g o, dac., the second following the lines a c', b 7c, c Z, (Z m, e n, f o, dac., the third following the lines b h, c c', d70,

e Z, fm, g fn, &c., which arrangement is revertical series, the horizontal series being in
